Big oops from IO Data. Looks like the Japanese company has shipped a batch of external hard drives that come with a big surprise—a Windows worm. The Tompai-A worm was found in the hard drives, which actually turns the host PC into a malware factory. But because it's not some crazy, brand-new strand of infection, any anti-malware program should guard against it. And hey, it's not here in the US, is it? Finally, the Japanese get something we actually don't want.
